PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The producer-core premise is correct and the slice is narrowly scoped, but the emitted diagnosisId is not target-scoped. Because recovery diagnosis graph nodes are keyed from diagnosisId, this should be fixed before the new recovery class becomes a consumed event source.

Peer-Review Opening: This is the right first leaf for #14026/#14046: pure detect-producer, additive data-integrity class, compose-service target identity, and no repair mutation. The blocker below is small but real contract hygiene.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14074 ticket, #14075 PR body/conversation, changed-file list, exact-head diff at 5cdb47cc64, current recovery diagnosis contract in recoveryRunStateStore.mjs, existing ContainerHealthDiagnosisService diagnosis-id pattern, and narrow Memory Core prior-art sweep for the #14074/#14075 data-integrity producer framing.
• Expected Solution Shape: A correct first leaf should take an injected auditChromaVectorCoverage() result and emit a contract-valid recovery-diagnosis | null without touching Chroma or repair paths. It must keep per-collection drift as evidence/details, target the existing compose-service identity, extend only the recovery class enum, and make the diagnosis identity stable and target-scoped.
• Patch Verdict: Mostly matches. The implementation is pure, detect-only, enum-validating, and test-covered; however diagnosisId is only data-integrity:coverage-drift:${observedAt} while targetIdentity varies by serviceId.
• Premise Coherence: Coheres with V-B-A and blast-control: the PR does not overreach into runtime wiring or actuator repair. The ID gap conflicts with the graph-contract side of the same premise, because a data-integrity diagnosis must remain distinguishable by target service.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14074
• Related Graph Nodes: #14026, #14046, #14061, #14056, #13999

🔬 Depth Floor

Challenge: buildDataIntegrityCoverageDiagnosis() takes a serviceId, but the diagnosis id ignores it. Existing producers include the target/service key in the stable diagnosis id (container-health:${serviceKey}:${recoveryClass}:${observedAt}), and recoveryRunStateStore derives the recovery diagnosis graph node id directly from diagnosisId.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: scoped to the producer-core and explicitly defers runtime wiring.
• Anchor & Echo summaries: correctly state pure detect-only behavior and compose-service targeting.
• [RETROSPECTIVE] tag: N/A.
• Linked anchors: #14074 establishes this producer leaf and #14061 remains the sink consumer.

Findings: Pass on framing; required action is mechanical event-identity contract, not rhetorical drift.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None. Exact-head bootstrap and targeted unit verification passed locally.
• [RETROSPECTIVE]: Recovery diagnosis producers should include the target/service identity in stable diagnosisId values, because the graph projection keys diagnosis nodes as recovery-diagnosis:${diagnosisId} while target identity is only stored as node properties.

🎯 Close-Target Audit

• Close-targets identified: #14074
• For #14074: confirmed not epic-labeled (enhancement, ai, architecture).

Findings: Pass.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger matrix.
• Implemented PR diff matches the Contract Ledger exactly (no drift).

Findings: Contract gap flagged. The ledger says the producer returns a recovery-diagnosis | null; for that event contract, diagnosisId needs the same target scoping as the targetIdentity it represents. Current implementation at ai/daemons/orchestrator/services/dataIntegrityCoverageDiagnosis.mjs:50 omits serviceId.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line.
• Achieved evidence matches this leaf's close-target ACs: pure producer behavior is covered by L2 unit tests; runtime wiring is explicitly out of scope and called out in Post-Merge Validation.
• Evidence-class collapse check: PR language does not promote the L2 producer proof into runtime wiring proof.

Findings: Pass.

🔌 Wire-Format Compatibility Audit

Findings: One blocker. The new data-integrity event is additive and validates against RECOVERY_CLASSES, but the stable event id should be collision-resistant across serviceId values. recoveryRunStateStore.getRecoveryDiagnosisGraphNodeId() returns recovery-diagnosis:${diagnosisId}, and graph projection uses that id for the diagnosis node; two compose-service targets observed in the same millisecond would collapse to the same diagnosis node if the id omits serviceId.

🔗 Cross-Skill Integration Audit

• No skill file, MCP tool, or workflow primitive is changed.
• The new consumed surfaces are documented in the PR/ticket Contract Ledger.
• Runtime wiring remains a separate follow-up rather than being silently implied here.

Findings: Pass; no cross-skill update required for this producer-core slice.

🧪 Test-Execution & Location Audit

• Branch checked out locally: exact-head worktree tmp/review-14075 at 5cdb47cc64.
• Canonical Location: new spec is under test/playwright/unit/ai/daemons/orchestrator/services/, matching the new orchestrator service file.
• If a test file changed: ran the specific test file.
• If code changed: verified related syntax and tests.

Findings:

• node --check ai/daemons/orchestrator/services/dataIntegrityCoverageDiagnosis.mjs passed.
• npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/dataIntegrityCoverageDiagnosis.spec.mjs passed: 5 passed (32.7s).
• GitHub checks are green at 5cdb47cc64: PR body lint, AiConfig lint, CodeQL, JSDoc, retired-primitives, unit, integration-unified.

📋 Required Actions

To proceed with merging, please address the following:

• Include the target service identity in the diagnosisId emitted by buildDataIntegrityCoverageDiagnosis() and add a focused unit assertion proving two different serviceId values at the same observedAt produce distinct diagnosis ids. A shape mirroring the existing producer precedent would be data-integrity:coverage-drift:${serviceId}:${observedAt} (sanitize if needed, matching the local convention you choose).

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 88 - Correct producer-core boundary, target-kind blast-control, and detect-only shape; deduction for an event identity that is not target-scoped.
• [CONTENT_COMPLETENESS]: 90 - Ticket/PR contract ledgers are present and accurate at the surface level; deduction because the stable id aspect of the event contract is not documented or tested.
• [EXECUTION_QUALITY]: 84 - Exact-head tests and CI pass, but the untested same-timestamp/multi-service case can collide in graph projection.
• [PRODUCTIVITY]: 86 - Delivers the DETECT producer leaf, pending a small fix before it is safe as a consumed diagnosis source.
• [IMPACT]: 82 - High-value first step toward catching metadata-without-vector corruption before false-green health reports.
• [COMPLEXITY]: 30 - Small additive producer and enum extension; main complexity is preserving the recovery-event identity contract.
• [EFFORT_PROFILE]: Quick Win - Small code delta with significant recovery-gate value once the id contract is fixed.

Fix the diagnosis id scoping and the added regression assertion; I expect this to be a fast re-review.
